Remember that all objectives must be finished in one round. If you get eliminated at any point during the raid, the quest progress will reset and you'll need to ARC Raiders Coins start again.

Find MANTIKOR's Underground Facilities

Your first task after spawning on the Blue Gate map is to head toward the Security Wing. The easiest way to reach this location is through the Reinforced Reception area, which is positioned on the northern side of the map.

Once you arrive at Reinforced Reception, look for a zipline leading downward. This zipline provides direct access to the Security Wing, allowing you to quickly enter the underground section of the facility.

After descending into the Security Wing, proceed through the main entrance door and continue forward. You'll encounter a tunnel shortly afterward. Follow the tunnel path and then turn right once you exit it. Not far from the tunnel exit, you should notice a locked room on the right side-this is the location tied to your quest objective.

However, the door won't open normally. You'll need to solve a small environmental puzzle before gaining entry.

Find a Way Into the Locked Room in the Security Wing

The locked room in the Security Wing requires three batteries to power the door's control system. Next to the door's activation button, you'll see three empty sockets, each meant to hold a battery.

Your task is to locate these batteries scattered throughout the Security Wing and bring them back to the door.

Common Battery Spawn Locations

While battery spawns can vary slightly between raids, several locations tend to appear more frequently:

Under the staircase in the main lobby of the Security Wing

Mounted on the wall near a breachable door

Various nearby utility areas and storage spots within the wing

Explore the area carefully and keep an eye out for the distinctive battery units. Once you find one, pick it up and carry it back to the locked door.

Because you must transport each battery manually, this part of the quest can take some time. Be cautious while moving through the area, as enemy players or hostile machines could interrupt your progress.

After collecting all three batteries, insert them into the sockets beside the door. Once the final battery is placed, the door's power will activate, allowing you to open the locked room.

Search the Locked Room for Records on Project Heartwood

With the door unlocked, step inside the room and begin searching for the Project Heartwood records.

Move toward the back-right corner of the room, where you'll find a machine connected to archived recordings. Interact with it to ARC Raiders Coins for sale play the stored recording related to Project Heartwood. This step completes the investigation portion of the objective.
